【實施方式] 、根據SI式對電氣機器用線軸之複數個實施形態進行 β兄月再者’於複數個實施形態中，對相同之構成部位附以 相同之元件符號，且省略說明。 (第1實施形態） 首先，參照圖1〜圖14’針對第i實施形態進行說明。於 圖式中，以箭頭表示前後、左右及上下各個方向。為求方便， 100114237 6 201218580 於本說明書中，將以旋轉電機之軸向當作上下方向進行說 明。 第1實施形態之電氣機器用線軸，可應用於混合動力汽車 或電動汽車等所使用作為馬達及發電機之旋轉電機。電氣機 器用線軸，並不限定於此車輛之旋轉電機，亦可應用於變壓 ' 器或者反相器等其他電氣機器。 圖1〜圖4，係放大表示内轉子型旋轉電機11之一部分。 旋轉電機11，係如圖1所示具備定子12及轉子13。轉子 13,係包夾著既定之間隙而設於定子12之内周側。轉子13, 係具有轉子鐵心14及未圖示之永久磁石。且永久磁石，係 被埋入於轉子鐵心14中。而轉子鐵心14，係形成為圓筒形 狀，且於内周側設有未圖示之軸。 定子12，係具有定子鐵心15及線圈16。定子鐵心15， 係具有磁軛部17及複數個齒部18。磁軛部17，係形成為圓 筒狀。齒部18，係自磁軛部17之内周側之端部向中心軸側 突出。圖1，僅表示複數個齒部18中之1個齒部18。磁軛 部17，亦可代替完全之圓筒狀之外壁，而採用橢圓形或多 角形等各種形狀之外壁。齒部18，係如圖2〜圖4所示形成 • 為近似長方體形狀。而齒部18，係朝定子鐵心15之圓周方 . 向等間隔地配置。藉此，於定子鐵心15中相鄰之齒部18 之彼此間，如圖1、圖5及圖6所示，形成有凹槽15 a。 線圈16，係藉由於電氣機器用線軸21之主體部22的外 100114237 7 201218580 周側捲繞銅線等電線所形成。於第丨實施形態之情形，如圖 6所示設置有線圈16之電氣機器用線軸21，係自定子鐵心 15之内周側嵌入至齒部18。藉此，捲繞有電線之線圈， 夾持電氣機器用線軸21之主體部22而設於齒部18。圖6 所示之箭頭F，為嵌入電氣機器用線軸21之方向。 電氣機器用線軸21’係如圖1〜圖丨丨所示具有主體部 22、第一凸緣部23、第二凸緣部24及被契合部乃。主體部 22 ’係形成為筒狀，第丨實施形態之情形，主體部^， 係形成為方筒狀。主體部22，並不限定於方筒形，而可根 據齒部18之形狀，任意地設定為圓筒狀或橢圓筒狀等。主 體部22,係如目7〜圖u所示具有上側壁瓜、下側壁创、 右側壁22c及左側壁22d。上側壁瓜、下側壁饥、右側 壁22c及左側壁22d，係於内側形成有空間叫。此空間仏， 與齒部18之形狀幾乎—致，且設定為僅略大於齒部a。上 側壁22a及下側壁22b ’係如圖2〜圖4所示於將電氣機器 料軸嵌人齒部18時，分別位於定子鐵心15之抽向之 W X，右側壁22c及左側壁22d於將電氣機器用線轴 21嵌入齒部18時，係位於定子鐵心15之凹槽15a内。 於此，由上側壁22a、下側壁22b、右側壁22c及左側壁 22d所構成之主體部22，係由例如絕緣薄膜等絕緣材料所形 成。此絕緣薄膜為例如由通用絕緣材料之薄膜所組成或由積 層絕緣材料之薄膜所組成等’係具有公知的絕緣性之薄膜。 100114237 201218580 作為絕緣薄膜，可列舉例如美國杜邦(Du Pont)公司生產之 NOMEX(註冊商標）等醯胺紙、聚苯硫醚薄膜、聚亞醯胺薄 膜、聚二醚酮薄膜、及聚對苯二甲酸乙二醇酯薄薄膜等塑膠 ，薄膜。尤其，積層醯胺紙與塑膠薄膜之積層薄膜，係具有優 異之耐熱性、絕緣性、及機械特性等。因此，積層醯胺紙與 塑膠薄膜之積層薄膜，可適宜地用作形成電氣機器用線軸 21之主體部22的絕緣薄膜。尤其以積層醯胺紙與聚笨硫喊 薄膜之積層薄膜、及積層醯胺紙與聚亞醯胺薄膜之積層薄 膜’作為形成電氣機器用線軸21之主體部22的絕緣薄膜為 更佳。又’如圖14(a)所示’形成主體部22之絕緣薄膜的厚 度T〗’係設定為〇 〇5〜0.5 mm。而形成此主體部22之絕緣 薄膜的厚度Ti<係以0.1〜0.4 mm為佳，以〇.2〜〇,3 mm為 較佳。形成主體部22之絕緣薄膜的厚度Tl，若未滿〇.〇5mm 則強度不足。因此，於將電線捲繞於電氣機器用線軸21時， 易發生招致主體部22之變形等異常。另一方面，形成主體 部22之絕緣薄膜的厚度Tl ’若超過0.5 mm，則主體部22 之厚度過大。因此，因為電線之匝數將減少而使得疊片因數 降低，同時由於導熱性之降低使散熱性亦降低。主體部， . 係與第一凸緣部23及第二凸緣部24連接為一體。 • 電氣機器用線軸21，係具備複數個契合孔22e。具體而 言，契合孔22e，分別設於主體部22中轴向之兩側之端部。 契合孔22e，係如圖5及® 7所示將形成主體部22之絕緣 100114237 9 201218580 薄膜朝厚度方向、即朝徑向貫穿。契合孔22e，係例如剖面 形狀為圓形。 形成主體部22之絕緣薄膜，係於表面施以表面處理。具 體而言，形成主體部之絕緣薄膜之表面，係被施以例如電漿 處理、電暈處理或化學處理等。此等處理，可僅施以一種， 或亦可組合複數種處理。藉由對形成主體部22之絕緣薄膜 施以表面處理，使絕緣薄膜之表面之親水性等性質得到改 質。因此，例如絕緣薄膜之表面伴隨可濕性之提升，而使得 黏著性提升。其結果，使由絕緣薄膜所形成之主體部22與 第一凸緣部23及第二凸緣部24，更牢固地接合。作為表面 處理，為得到處理之簡便性及可潤濕性之提升等效果之提 高，尤其以電漿處理為佳。於本說明書中，係以電漿處理為 例進行說明。 第一凸緣部23及第二凸緣部24，限制被設於主體部22 之線圈16之移動。具體而言，設於主體部22之線圈16， 係於定子鐵心15之徑向發生偏移。所以，第一凸緣部23 及第二凸緣部24，係於主體部22之軸向之端部與線圈16 接觸，限制線圈16之移動。 第一凸緣部23及第二凸緣部24,係任一者均自主體部22 向徑向外側突出形成為環狀。即，第一凸緣部23，係使内 周側之緣部與主體部22成為對向。第一凸緣部23，係設於 主體部22之軸向之端部。具體而言，第一凸緣部23，於將 100114237 10 201218580 電氣機器用線軸21嵌入齒部18時，係位於與定子鐵心15 之磁軛部17成為對向之側。第一凸緣部23，係於内周側具 有複數個被契合部25。被契合部25,於將第一凸緣部23 安裝至主體部22時，進入至上述主體部22所形成之契合孔 22e。被契合部25，係形成為對應契合孔22e之圓柱狀。被 契合部25，係可根據契合孔22e之形狀變更形狀。例如使 契合孔22e之剖面為四角形狀時，被契合部25係形成為四 角柱狀。 第二凸緣部24，係和第一凸緣部23同樣地使内周側之緣 部與主體部22為對向。第二凸緣部24，係設於主體部22 之軸向之另一端部、即與第一凸緣部23為相反側之端部。 具體而言，第二凸緣部24，於將電氣機器用線軸21嵌入齒 部18時，係位於定子鐵心15之中心側。第二凸緣部24， 係設定為使於定子鐵心15之圓周方向之全長小於第一凸緣 部23。此原因，在於第二凸緣部24，較第一凸緣部23更位 於定子鐵心15之中心側。即，電氣機器用線軸21，係相對 於定子鐵心15之中心被嵌入至形成放射狀之齒部18。因 此，於與定子鐵心15之圓周方向相鄰之電氣機器用線軸21 之間隔，係越接近定子鐵心15之中心側即第二凸緣部24 側越小。藉此，為了不使相鄰之同為電氣機器用線軸21之 第二凸緣部24者互相接觸，第二凸緣部24係設定為使定子 鐵心15之圓周方向之全長小於第一凸緣部23。第二凸緣部 100114237 11 201218580 24，係與第一凸緣部23同樣地於内周側具有複數個被契合 部25。被契合部25，於將第二凸緣部24安裝至主體部22 時，係進入至主體部22所形成之契合孔22e。第二凸緣部 24之被契合部25之形狀，係與第一凸緣部23相同。 第二凸緣部24，亦可使轉子13側之面與轉子13之外壁 為同心圓狀地彎曲。又，第一凸緣部23，亦可使磁軛部17 側之面與磁軛部17之内壁為同心圓狀地彎曲。尤其藉由使 第一凸緣部23之磁軛部17側之面與磁軛部17之内壁為近 似之曲度，電氣機器用線軸21之磁輛部17側之端部，可根 據磁輛部17之内壁而決定位置。 第一凸緣部23、第二凸緣部24及被契合部25，係由合成 樹脂所形成。於此，作為合成樹脂，例如以聚苯硫鱗樹脂 (Polyphenylene Sulfide Resin，PPS 樹脂）、丙烯腈-丁二稀-苯乙烯共聚物樹脂、聚亞醯胺系樹脂、聚對苯二甲酸乙二醇 酯系樹脂、及聚縮醛系樹脂等為佳。此第一凸緣部23、第 二凸緣部24及被契合部25，係藉由例如插入成形而與主體 部22形成為一體。第一凸緣部23及第二凸緣部24之厚度， 係為任意。於第1實施形態之情形，第一凸緣部23及第二 凸緣部24，係如圖14所示將其厚度T2設定為2〜3 mm。 第一凸緣部23及第二凸緣部24之厚度T2，較期望係於可 成形之範圍盡可能設定為較小。如此藉由減少第一凸緣部 23及第二凸緣部24之厚度Τ2，電氣機器用線轴21之主體 100114237 12 201218580 部22係使軸向之全長得以擴大。其結果，使捲繞 22之電線之匝數增加，可提高電線之疊片因數。；體部 被契合部25，係於第一凸緣部23及第二 • 之同時被填充於主體部22之契合孔22e。藉此4形成 25,分別與第一凸緣部23及第二凸緣部24_兔破契合部 此藉由於第一凸緣部23及第二凸緣部24形成為^體。如 合部25填充至契合孔❿，第一凸緣部 门時將被契 :被契合㈣’進入契合孔22e而成為做:凸::24 第凸緣部23及第二凸緣部24,係與主體部2二果， 連接。 可牢固地 ::機益用線轴21，係如圖5所示具備填充構 充構件26，於千26。填 於主體部22之内周侧、第一 真 側及第二凸绫邱h > I 之内周 凸緣邛24之内周側填埋主體部2 23及第二凸緣部2 /、第—凸緣部 怂氺道丸 之間的回低差。此填充構件26，較期望 '、，，、、性優異之材料所形成。填充構件％，較期望係為 例如^熱可紐樹脂或滑麟溫度越上錢動性越增加者。 接著，針對上述電氣機器用線軸21之成形所使用的插入 成形模具參照圖12進行說明。 圖12所示之插入成形模具31，係具備基座部32、下模 . 33及上模34。下模33，係設於基座部32之上方。上模％， 係°又於下& 33之上方。基座部32 ’係保持下模33及上模 34。基座部32 ’係具有用於決定電氣機器用線軸21之主體 100114237 13 201218580 部22之位置的擋塊部35。擋塊部35，係為與定子鐵 之#部18幾乎相同形狀之四角柱狀。基座部32，r 、 ，係具有向 上方突出之複數根突出銷36。突出銷36，係用於自+ 取出已成形之電氣機器用線軸21者。 下模33 下模33，係由一對塊狀之可動下模37所構成 下模37，設於基座部32之上方，且沿基座部 對可動 z之上面移 動而打開模具。圖12所示之箭頭γ，表示打開模具之方向。 可動下模37具有相當於電氣機器用線軸21之大致—半=升， 狀的切口38，。―對可動下模37,藉由將此等結合形Ζ 納電氣機器用線軸21的模腔38。於可動下模37之上方 設有連接可動下模37與模腔38的喷嘴39。噴幻9，例如 將炼融之PPS等樹脂供給模月空38。第一凸緣部^及第二凸 緣部24，係由供給自喷嘴39之樹脂所形成。 上模34，具有貫穿上下之線軸洗道4()。㈣之樹脂，經 由此上模34之線轴液道4〇而供給至下模％之喷嘴％。於 上模34之上端’形成有連接於線减道4()之貯存部w。 自外部供給之熔融之樹脂儲存於此貯存部4卜並藉由結合 上模=與下帛33,使線減道4()之下端部連接於喷嘴： 接著，參照圖13針對電漿處理進行說明。 電漿處理，係利用藉由對電極之間施加直流或交流之高電 壓所生成之放電進行。藉由施加高電壓而產生之放電，係於 大氣壓下之電暈放電或者於真空中之輝光放電等。形成主體 100114237 201218580 部22之絕緣薄膜，藉由暴露於由此等所產生之放電進行電 漿處理。電漿處理，以於處理氣體之選擇範圍較廣之真空中 的處理為佳。又，電漿處理，作為處理氣體，係將氦氣、氖 氣、氬氣、氮氣、氧氣、二氧化碳氣體、空氣、及水蒸氣等 « 以單獨或者混合之狀態進行使用。其中更以氬氣、二氧化碳 ' 氣體，係因放電開始效率方面為佳。於電漿處理中之處理氣 壓，為0.1 Pa〜1330 Pa之氣壓範圍，以1 Pa〜266 Pa之範 圍為更佳。 圖13所示之電漿處理機51，係具有可密閉之處理室52。 處理室52，係將處理用輥53收容於内部。電極54，係於此 處理用輥53之周圍形成少許之間隙而予以包圍。處理用輥 53，係予以接地。電極54,連接於高頻電源55。處理室52， 藉由使内部連接於未圖示之真空泵的閥門56之開啟而減 壓。與此同時，處理室52,藉由連接於未圖示之氣體供給 源的閥門57之開啟而供給有處理用之氣體。處理室52，設 有檢測内部之氣壓的壓力計58。 捲繞為輥狀之絕緣薄膜42，係自供給部59抽出。所抽出 之絕緣薄膜42，一面由處理室52内之複數個導引輥60所 . 導引一面於處理用輥53捲曲將近一周。此時，絕緣薄膜42， - 通過與電極54之間的處理部分，且於此處被施以電漿處 理。然後，經施以電漿處理之絕緣薄膜42，一面由導引輥 60所導引一面被捲取於捲取部61。此時，絕緣薄膜42，於 100114237 15 201218580 單面或雙面被施以電漿處理。於對絕緣薄膜42之單面施以 電漿處理時，將經施以電漿處理之面配置於主體部22之外 周側。 接著，針對電氣機器用線轴21之製造步驟參照圖12進行 說明。 構成主體部22之絕緣薄膜42，係進行表面處理步驟。表 面處理步驟，為例如使用上述之電漿處理機51之電漿處 理。經電漿處理之薄膜狀之絕緣薄膜42，係如圖12(a)所示 為展開主體部22之形狀、即裁切為長方形狀。裁切後之絕 緣薄膜42之長邊之長度P，相當於將上側壁22a之左右方 向之長度、左側壁22d之上下方向之長度、下側壁22b之左 右方向之長度、右側壁22c之上下方向之長度，根據必要加 上塗膠區域之長度。又，裁切後之短邊的長度Q，相當於主 體部22之前後方向、及上側壁22a之前後方向的長度。於 此，絕緣薄膜42之厚度，係設定為0.05〜0.5 mm。 絕緣薄膜42 ,於成形為將主體部22展開之形狀時，或於 成形之前後，在長邊之兩端分別形成有相當於契合孔22e 之孔。契合孔22e，既可於使絕緣薄膜42成形為既定之形 狀後進行，亦可事先於形成契合孔22e後，進行絕緣薄膜 42之成形。又，亦可藉由使用模具之衝壓等，同時進行絕 緣薄膜42之成型與契合孔22e之形成。 經成形之絕緣薄膜42，係如圖12(b)所示成形為相當於主 100114237 16 201218580 體部22之形狀。於第1實施形態中，絕緣薄膜42，成形為 方筒狀。當絕緣薄膜42包含塗膠區域時，經彎折為方筒狀 之絕緣薄膜42，將使塗膠區域位於上側壁22a或下側壁 22b。又，於使主體部22成形時，亦可將黏著劑等塗佈於塗 膠區域，而於插入成形前暫時固定絕緣薄膜42。藉此，使 " 所成形之絕緣薄膜42，於插入成形時減少形變。進行此等 絕緣薄膜42之成形、契合孔22e之形成及主體部形狀之成 形的步驟，係相當於主體部整形步驟。 經成形為筒狀之絕緣薄膜42,係如圖12(c)及圖12(d)所 示，於下模33開啟之狀態、即於可動下模37相互分開之狀 態嵌入至擋塊部35。將此絕緣薄膜42嵌入至下模33之擋 塊部35之步驟相當於主體部配置步驟。經成形為筒狀之絕 緣薄膜42，於嵌入至擋塊部35時，自基座部32略微分開。 藉由分開配置如此所成形之絕緣薄膜42與基座部32，於主 體部22之軸向將插入成形時之樹脂注入至端部的外側。其 結果，主體部22，係使於軸向之端部的強度得以提高。當 將成形為筒狀之絕緣薄膜42配置於擋塊部35時，如圖12(e) 所示將結合可動下模37，而形成模腔38。藉此，筒狀之絕 • 緣薄膜42，係收容於模腔38。此步驟，相當於下模固定步 . 驟。 當將成形為筒狀之絕緣薄膜42收容於模腔38時，如圖 12(f)所示將使上模34安裝於下模33之上面。然後，將熔融 100114237 17 201218580 之樹脂，注入至上模34之儲存部41。注入至貯存部41之 樹脂，係經由線軸澆道40及喷嘴39而供給至模腔38。藉 此，將成形為筒狀之絕緣薄膜42即使主體部22作為插入件 而進行插入成形，主體部22係與第一凸緣部23、第二凸緣 部24及被契合部25成形為一體。即，藉由熔融之樹脂之注 入，以主體部22作為嵌入件而使第一凸緣部23、第二凸緣 部24及被契合部25與主體部22成形為一體。此步驟，係 相當於凸緣部成形步驟。藉由此插入成形，利用樹脂之注入 所形成之被契合部25，進入至主體部22的契合孔22e。因 此，自第一凸緣部23及第二凸緣部24 —體地突出之被契合 部25，係與契合孔22e成為嚙合狀態。 藉由預先對絕緣薄膜施以電漿處理等表面處理，使主體部 22得以提高表面之潤濕性及黏著性。因此，形成第一凸緣 部23及第二凸緣部24之熔融之樹脂，係確保沿絕緣薄膜 42之流動性。其結果，形成第一凸緣部23及第二凸緣部24 之樹脂，係於充分之範圍黏著於主體部22。藉此，主體部 22與凸緣部充分地接合，使於成形後之第一凸緣部23及第 二凸緣部24之破裂等得以減少。 於由插入成形之凸緣部成形步驟後，上模34係自下模33 取出。然後，下模33之可動下模37係開啟模具。此時，藉 由將基座部32之突出銷36自基座部32突出，使得電氣機 器用線軸21自基座部32取出。 ]〇〇]14237 18 201218580 再者，於上述製造步驟之說明中，雖然已對在實於主體部 整形步驟前施以電漿處理等表面處理步驟之例進行說明，但 亦可於進行主體部整形步驟後，且於進行凸緣部成形步驟前 施以表面處理步驟。例如表面處理，亦可於使絕緣薄膜42 β 成形為既定之尺寸後，對此絕緣薄膜42施行。又，亦可於 ： 進行主體部整形步驟前，及於進行主體部整形步驟後，且於 進行凸緣部成形步驟前之任一時期，實施表面處理步驟。 接著，針對將線圈16安裝於定子鐵心15之齒部18之步 驟參照圖1〜圖4、圖6、及圖11進行說明。 由上述加工所得如圖11所示之電氣機器用線軸21，係於 主體部22之外周捲繞有電線。藉此，電氣機器用線軸21 係如圖6所示於主體部22之外周設有線圈16。又，電氣機 器用線軸21，係於主體部22之内周側填充有填充構件26。 設有線圈16且填充有填充構件26之電氣機器用線軸21， 如圖6中之箭頭F所示係自定子鐵心15之内周側嵌入至定 子鐵心15之齒部18。藉此，線圈16，成為夾持電氣機器用 線軸21且，被集中捲繞於齒部18之狀態。此時，如圖1〜 圖4所示，齒部18，係收容於較主體部22之右側壁22c及 - 左側壁22d更靠内側。另一方面，主體部22之上側壁22a . 及下側壁22b，在定子鐵心15之軸向位於較齒部18之全長 更靠外側。又，主體部22與齒部18之間，係由填充構件 26所填埋。定子鐵心15,係於所有齒部18安裝有設有線圈 100114237 19 201218580 16之電氣機器用線軸21。 於此’參照圖14針對電線之疊片因數進行說明。圖I4(b) 所示之習知之電氣機器用線軸101 ’係藉由例如射出成形等 且利用相同之樹脂使主體部102與第一凸緣部103及第二凸 緣部104無接縫地形成為一體。此情形，主體部102之厚度 T 〇，係因成形時之限制必須確保於以樹脂一體成形後至少不 發生破裂之程度的尺寸《因此，主體部102之厚度T〇，係 要求為例如TQ=1〜3 mm左右。 另一方面，於本實施形態之情形，主體部22中之右侧壁 22c及左側壁22d，係由厚度T〗為1 = 0.05 mm〜0.5 mm之 絕緣薄膜所形成。因此，本實施形態之電氣機器用線軸21 之電線的疊片因數，係與習知構成之電氣機器用線軸101 相比，可提高相當於(To—Ti)之量。 又’通常，於電流1(A)流過圓形之線圈導體時，線圈之軸 中心Ο之磁通密度B，係以「B= /z〇Nl/2r :其中，#〇為真 空之磁導率，N為每lm之匝數，1為線圈之長度，r為線圈 之半徑」表示。第1實施形態之主體部22，如上所述與習 知之主體部102相比為較薄。因此，設於第1實施形態之主 體部22之外周的線圈16之半徑r!，且較習知之線圈的半徑 r〇減小相當於(τ〇—Τι)之量。其結果，使用第1實施形態之 電氣機器用線軸21的線圈16，係與習知相比可提高磁通密 度。因此，第1實施形態之電氣機器用線軸21，自磁通密 100114237 20 201218580 度之觀點亦可實現旋轉電機u之旋轉效率之提高。 根據以上所說明之第1實施形態，嵌入至定子鐵心15之 齒部18之電氣機器用線軸21之主體部22,係由右側壁22c • 及左側壁22d之厚度為〇 〇5〜〇.5 mm之絕緣薄膜所構成。 • 因此，主體部22之右側壁22c及左側壁22d之厚度，係較 以習知之插入成形所形成之線軸為薄。因此，可將更多之電 線捲繞於電氣機器用線軸21之主體部22，而提高電線之疊 片因數。又，因為主體部22變薄，故由電線所產生之熱能 容易經由較薄之主體部22傳達至定子鐵心15。因此，可使 由電線所產生之熱能迅速地擴散，而提高散熱性。藉由提高 散熱性，旋轉電機11可實現高輪出化及高效率化。 第1實施形態之t氣機器用線軸21，係於主體部22之轴 向之端部具有契合孔22e。設於主體部22之軸向之端部的 第一凸緣部23及第二凸緣部24，分別使被契合部乃進入 至契合孔22e。藉此，主體部22與第一凸緣部23之接合強 度、及主體部22與第二凸緣部24,係以較高之強度所接合。 因此，可減少第一凸緣部23及第二凸緣部24自主體部22 之脫落。 於第1實施形態中，第一凸緣部23及第二凸緣部Μ，係 以主體部22為插入品進行插入成形。所以，即便於主體邛 22與第一凸緣部23及第二凸緣部24係由不同之材料所= 成時，亦可使製造變容易。與此同時，藉由插入成\斤^ >第·一 100114237 21 201218580 凸緣部23及第二凸緣部24，得以確保充分之厚度。因此， 可提高第一凸緣部23及第二凸緣部24之強度。又，主體部 22,係與第一凸緣部23及第二凸緣部24接合為一體。因此， 即便於此等係以不同材料所形成時，電氣機器用線軸21亦 可容易地安裝於定子鐵心15等構件。 於第1實施形態中，在主體部22之内周側設有填充構件 26。填充構件26，填埋主體部22與第一凸緣部23及第二 凸緣部24之間的高低差。藉此，當將電氣機器用線軸21 安裝於齒部18時，主體部22與齒部18之間的間隙，將由 具有流動性之填充構件26所填埋。所以，由構成線圈16 之電線所產生之熱能，係經由主體部22自填充構件26傳達 至定子鐵心15。因此，可使線圈16之散熱性提高，抑制線 圈16之溫度上升。 於第1實施形態中，在進行主體部整形步驟之前，或在進 行主體部整形步驟後，且在進行凸緣部成形步驟之前，對絕 緣材料之表面施以改善可濕性之表面處理。藉此，於插入成 形時，形成第一凸緣部23及第二凸緣部24之熔融之樹脂， 將變得容易沿形成主體部22之絕緣材料流動。藉此，形成 第一凸緣部23及第二凸緣部24之樹脂與形成主體部22之 絕緣材料，可確保高黏著性。因此，可提高主體部22與第 一凸緣部23及第二凸緣部24之接合強度，同時可減少於成 形後之破裂等。 100114237 22 201218580 (第2實施形態） 於圖15表示第2實施形態之電氣機器用線軸21之重要部 位。第一凸緣部23及第二凸緣部24,具有大致對稱之構造。 因此，於圖15中係對第一凸緣部23之周圍進行圖示，而第 二凸緣部24之圖示及說明則省略。 第一凸緣部23，係如圖15所示具有一對夾持片23a。一 對夾持片23a，係設於位在主體部22之厚度方向之夾持主 體部22之位置。夾持片23a，係與第一凸緣部23同時地， 由與第一凸緣部23相同之樹脂成形為一體。一對夾持片23a 中之一方，於主體部22之徑向上位於内側。夾持片23a之 另一方，位於主體部22之徑向之外側。 於第2實施形態之情形，契合孔22e，係使於主體部22 之徑向之兩端部，對向於此等一對之夾持片23a。即，契合 孔22e，使一端部對向於内周側之夾持片23a，並使另一端 部對向於外周側之夾持片23a。然後，自第一凸緣部23突 出之被契合部25，係於主體部22之徑向連接此等一對夾持 片23a。即，被契合部25，係貫穿契合孔22e且於主體部 22之徑向連接一對同為夾持片23a者。被契合部25，係兩 端部之任一者均與夾持片23a形成為一體。即，於形成第一 - 凸緣部23時，成為第一凸緣部23之熔融之樹脂，係形成夾 持片23a，同時使一部分進入至契合孔22e，而形成被契合 部25。藉此，第一凸緣部23，使用樹脂將夾持片23a及被 100114237 23 201218580 契合部25形成為一體。 於第2實施形態中，主體部22，由為一體之夾持片23a 及被契合部25，以面向圓周方向且在複數個位置固定於第 一凸緣部23。因此，可進一步提高主體部22與第一凸緣部 23之接合強度。於第2實施形態之情形，第二凸緣部24， 係與第一凸緣部23為同樣之構成。因此，第二凸緣部24 亦可與第一凸緣部23同樣地與主體部22牢固地接合。 (第3實施形態） 接著，於圖16及圖17表示第3實施形態之電氣機器用線 車由71。 圖16及圖17所示之電氣機器用線軸71，係具備補強用 之連結部72。連結部72，係連結第一凸緣部23與第二凸緣 部24之側壁。此連結部72，係與第一凸緣部23及第二凸 緣部24設為一體。連結部72，分別設於為上側壁22a之外 周側之上側及為下側壁22b之外周側之下側。 電氣機器用線軸71，與第1實施形態同樣地以主體部22 作為插入品進行插入成形。連結部72，於此插入成形時， 與第一凸緣部23及第二凸緣部24形成為一體。使連結部 72之厚度，在以插入成形可成形之範圍内任意設定。連結 部72之厚度，例如，設定為1〜3 mm。 於第3實施形態中，連結部72，係設於第一凸緣部23與 第二凸緣部24之間。此連結部72，具有較主體部22更大 100114237 24 201218580 之厚度。所以，主體部22，特別針對來自軸向之壓縮使強 度增加。藉此，主體部22，係使變形得以減少。因此，可 提高電氣機器用線軸71之強度。 於第3實施形態中，連結部72，分別設於上側壁22a及 下侧壁22b之外側。另一方面，主體部22，右側壁22c及 左侧壁22d係由絕緣薄膜所形成。所以，即便設置連結部 72亦不會對構成線圈16之電線之匝數造成影響。因此，可 一面提高強度一面提高電線之疊片因數。 (第4實施形態） 於圖18及圖19表示第4實施形態之電氣機器用線軸81。 圖18及圖19所示之電氣機器用線軸81，係具備補強用 之連結部82。連結部82,為連結第一凸緣部23與第二凸緣 部24之側壁。此連結部82，與第一凸緣部23及第二凸緣 部24設為一體。連結部82，分別設於為上側壁22a之内周 側之下側及為下側壁22b之内周側之上側。 電氣機器用線軸81，與第1實施形態同樣地以主體部22 作為插入品進行插入成形。連結部82，於此插入成形時， 與第一凸緣部23及第二凸緣部24形成為一體。使連結部 82之厚度，在以插入成形可成形之範圍内任意設定。連結 部82之厚度，例如，設定為1〜3 mm。 第4實施形態，亦與第3實施形態同樣地，可一面提高電 線之疊片因數一面提高電氣機器用線軸81之強度。 100114237 25 201218580 (第5實施形態） 於圖20表示第5實施形態之雷名地 电礼機器用線軸91。 第5實施形態之電氣機器用線細 來軸91 ’以壓製成形，代替 上述複數個實施形態之插人成形。於第5實施形態之情形， 主體部22，如圖2〇⑻及圖2〇(6)所示使車由向之兩端部分別 向外側彎折。藉此，主體部22，抓红丄 於轴向之兩端部具有法蘭 部22f。契合孔22e ’配置於法蘭部） 闹。丨4 22f。又，於第5實施形 態之情形，第一凸緣部23及第二 6緣部24，任一者均為2 層構造。 第一凸緣部23，係具有2片之坌n 磁& 〈弟一凸緣部片23b及黏著 構件92。第一凸緣部片23b，如 货π

體部22設為一體。此時，契合孔22e，配置於2片第二凸 緣部片24b之間。於第5實施形態之情形，2片第一凸緣部 片23b係相當於夾持片。又，2片第二凸緣部片24b，同樣 地相當於夾持片。 接著，針對第5實施形態之電氣機器用線軸91之製造步 驟進行說明。 構成主體部22之絕緣薄膜42，於表面被施以電漿處理等 表面處理。實施此表面處理之步驟，相當於表面處理步驟。 針對表面處理之詳細，係如第1實施形態所說明，而將說明 予以省略。當對絕緣薄膜42實施表面處理時，絕緣薄膜42, 如圖20(a)所示成形為展開主體部22之矩形。此時，絕緣薄 膜42，如圖20(b)所示亦可於長邊形成切口部42a。藉由形 成切口部42a，於後續步驟中使彎折變得容易。再者，實施 - 表面處理之時期，係與第1實施形態同樣地並未限定。 . 所成形之絕緣薄膜42，如圖20(b)所示被彎折為方筒狀， 而成形為主體部22。而且，所成形之絕緣薄膜42，係將軸 向之兩端向外周側彎折。藉此，形成法蘭部22f。此步驟， 100114237 27 201218580 相當於主體部整形步驟。 將於主體部整形步驟所形成之主體部22，轉移至凸緣部 成形步驟。具體而言，於主體部22之法蘭部22f，如圖20(e) 及圖20(f)所示依既定之順序積層第一凸緣部片23b及第二 凸緣部片24b、以及黏著構件92。其後，所積層之構件，係 藉由壓製成形，而成形為第一凸緣部23及第二凸緣部24。 第一凸緣部23，於自主體部22之軸向之端部側起依第一凸 緣部片23b、黏著構件92、主體部22之法蘭部22f、黏著 構件92及第一凸緣部片23b之順序進行積層後，以壓製成 形。藉此，黏著構件92將各構件進行黏著。同樣地，第二 凸緣部24，於自主體部22之軸向之端部側起依第二凸緣部 片24b、黏著構件92、主體部22之法蘭部22f、黏著構件 92及第二凸緣部片24b之順序進行積層後，以壓製成形。 藉此，黏著構件92，係將各構件進行黏接。 夾持主體部22之法蘭部22f之2片黏著構件92，係使一 部分進入至法蘭部22f之契合孔22e内。然後，法蘭部22f 之兩側之黏著構件92，於契合孔22e相互黏著。藉此，主 體部22之法蘭部22f，利用黏著構件92與第一凸緣部片23b 及第二凸緣部片24b牢固地接合。此時，黏著構件92中位 於契合孔22e内之部分，相當於被契合部。 所得之電氣機器用線軸91，與第一實施形態之電氣機器 用線軸21同樣地，被嵌入至圖1所示之定子鐵心15之齒部 100114237 28 201218580 18。藉此，使主體部22之絕緣薄膜位於被嵌入至定子鐵心 15之齒部18的電氣機器用線軸91之主體部22中至少位於 定子鐵心15内的部分。 根據上述之第5實施形態，與第1實施形態同樣地，主體 '部22之厚度得以減少。所以，於電氣機器用線轴91，得以 捲繞更多形成線圈16之電線。因此，可實現旋轉電機之高 輸出化及高效率化。 又，於第5實施形態中，代替插入成形，藉由壓製成形可 使第一凸緣部23及第二凸緣部24於主體部22形成為一體。 (第6〜第10實施形態） 以下，針對第6實施形態至第9實施形態進行說明。 於第6實施形態中，如圖21所示契合孔22g使剖面形成 為四角形狀。又，於第7實施形態中，如圖22所示契合孔 22h使剖面形成為三角形狀。而且，於第8實施形態中，如 圖23所示契合孔22i，使一部分朝絕緣薄膜42之外緣開口。 於第8實施形態之情形，契合孔22i，係以越靠近絕緣薄膜 42之内側使内徑越大為佳。如此之形狀之契合孔22i，係與 進入之被契合部25牢固地嚙合。因此，可使主體部22與第 • 一凸緣部23及第二凸緣部24相對地位置偏移較為減少。如 - 此，契合孔22g〜22i之形狀，係可任意設定。於第9實施 形態中，如圖24所示，電氣機器用線軸21，並未於主體部 22之内周側設置填充構件。例如於線圈16所產生之熱較少 100114237 29 201218580 時，如第9實施形態所示亦可省略填充構件2

[Embodiment] In the embodiment, the same components are denoted by the same reference numerals, and the description thereof is omitted. (First Embodiment) First, an i-th embodiment will be described with reference to Figs. 1 to 14'. In the figure, the front, back, left and right, and up and down directions are indicated by arrows. For convenience, 100114237 6 201218580 In this manual, the axial direction of the rotating machine will be described as the vertical direction. The electric machine bobbin according to the first embodiment can be applied to a rotary electric machine used as a motor and a generator for a hybrid vehicle or an electric vehicle. The bobbin for electric machines is not limited to the rotating electric machine of this vehicle, and can be applied to other electric machines such as transformers or inverters. 1 to 4 are enlarged views showing a part of the inner rotor type rotating electrical machine 11. The rotary electric machine 11 is provided with a stator 12 and a rotor 13 as shown in Fig. 1 . The rotor 13 is provided on the inner peripheral side of the stator 12 with a predetermined gap therebetween. The rotor 13 has a rotor core 14 and a permanent magnet (not shown). The permanent magnet is embedded in the rotor core 14. Further, the rotor core 14 is formed in a cylindrical shape, and a shaft (not shown) is provided on the inner peripheral side. The stator 12 has a stator core 15 and a coil 16. The stator core 15 has a yoke portion 17 and a plurality of teeth portions 18. The yoke portion 17 is formed in a cylindrical shape. The tooth portion 18 protrudes from the end portion on the inner peripheral side of the yoke portion 17 toward the central axis side. In Fig. 1, only one of the plurality of teeth 18 is shown. The yoke portion 17 may be a wall having various shapes such as an elliptical shape or a polygonal shape instead of the completely cylindrical outer wall. The tooth portion 18 is formed as shown in Figs. 2 to 4 and has an approximately rectangular parallelepiped shape. Further, the tooth portions 18 are arranged toward the circumference of the stator core 15 at equal intervals. Thereby, a groove 15a is formed between the adjacent tooth portions 18 of the stator core 15 as shown in Figs. 1, 5, and 6. The coil 16 is formed by winding a wire such as a copper wire on the outer side of the main body portion 22 of the bobbin 21 for electric equipment. In the case of the second embodiment, the electric machine bobbin 21 provided with the coil 16 as shown in Fig. 6 is fitted to the tooth portion 18 from the inner peripheral side of the stator core 15. Thereby, the coil of the electric wire is wound, and the main body portion 22 of the electric machine bobbin 21 is clamped to the tooth portion 18. The arrow F shown in Fig. 6 is the direction in which the bobbin 21 for electrical equipment is embedded. The electric machine bobbin 21' has a main body portion 22, a first flange portion 23, a second flange portion 24, and a fitted portion as shown in Fig. 1 to Fig. 1 . The main body portion 22' is formed in a tubular shape, and in the case of the second embodiment, the main body portion is formed in a rectangular tubular shape. The main body portion 22 is not limited to the rectangular tubular shape, and may be arbitrarily set in a cylindrical shape or an elliptical cylindrical shape depending on the shape of the tooth portion 18. The main body portion 22 has an upper side wall, a lower side wall, a right side wall 22c, and a left side wall 22d as shown in Figs. 7 to u. The upper side wall melon, the lower side wall hunger, the right side wall 22c and the left side wall 22d are formed with a space on the inner side. This space 几乎 is almost the same as the shape of the tooth portion 18, and is set to be only slightly larger than the tooth portion a. The upper side wall 22a and the lower side wall 22b are respectively located in the direction WX of the stator core 15 and the right side wall 22c and the left side wall 22d when the electric machine material shaft is embedded in the tooth portion 18 as shown in FIG. 2 to FIG. When the electric machine bobbin 21 is fitted into the tooth portion 18, it is located in the recess 15a of the stator core 15. Here, the main body portion 22 composed of the upper side wall 22a, the lower side wall 22b, the right side wall 22c, and the left side wall 22d is formed of an insulating material such as an insulating film. The insulating film is a film having a known insulating property, for example, composed of a film of a general insulating material or a film of a laminated insulating material. 100114237 201218580 As the insulating film, for example, a guanamine paper such as NOMEX (registered trademark) manufactured by Du Pont, Inc., a polyphenylene sulfide film, a polyimide film, a polydiether ketone film, and polyparaphenylene can be cited. Plastic film and film such as ethylene glycol diester film. In particular, laminated films of laminated polyamide paper and plastic film have excellent heat resistance, insulation properties, and mechanical properties. Therefore, the laminated film of the laminated polyamide paper and the plastic film can be suitably used as the insulating film for forming the main body portion 22 of the bobbin 21 for electrical equipment. In particular, it is more preferable that the laminated film of the laminated amide paper and the polystyrene film and the laminated film of the laminated guanamine paper and the polyimide film are formed as the insulating film for forming the main body portion 22 of the bobbin 21 for electrical equipment. Further, as shown in Fig. 14 (a), the thickness T of the insulating film forming the main body portion 22 is set to 〇 5 to 0.5 mm. The thickness of the insulating film forming the body portion 22 is Ti. < is 0. 1~0. 4 mm is better, with 〇. 2 to 〇, 3 mm is preferred. The thickness T1 of the insulating film forming the main body portion 22 is not full. 〇5mm is insufficient strength. Therefore, when the electric wire is wound around the bobbin 21 for electric equipment, an abnormality such as deformation of the main body portion 22 is likely to occur. On the other hand, the thickness Tl' of the insulating film forming the main body portion 22 exceeds 0. At 5 mm, the thickness of the main body portion 22 is too large. Therefore, since the number of turns of the electric wire is reduced, the lamination factor is lowered, and at the same time, heat dissipation is also lowered due to a decrease in thermal conductivity. Main body, . It is integrally connected to the first flange portion 23 and the second flange portion 24. • The bobbin 21 for electrical equipment has a plurality of matching holes 22e. Specifically, the engagement holes 22e are respectively provided at the ends of the main body portion 22 on both sides in the axial direction. The hole 22e is formed to penetrate the main body portion 22 as shown in Figs. 5 and 7, and the film is penetrated in the thickness direction, that is, in the radial direction. The fitting hole 22e is, for example, circular in cross section. The insulating film forming the main body portion 22 is subjected to a surface treatment on the surface. Specifically, the surface of the insulating film forming the main body portion is subjected to, for example, plasma treatment, corona treatment or chemical treatment. These treatments may be applied to only one type, or a plurality of types of treatments may be combined. By subjecting the insulating film forming the main body portion 22 to a surface treatment, properties such as hydrophilicity of the surface of the insulating film are improved. Therefore, for example, the surface of the insulating film is accompanied by an increase in wettability, so that the adhesion is improved. As a result, the main body portion 22 formed of the insulating film is more firmly joined to the first flange portion 23 and the second flange portion 24. As the surface treatment, in order to obtain an improvement in the ease of handling and the improvement in wettability, it is particularly preferable to use plasma treatment. In the present specification, the plasma treatment is taken as an example for explanation. The first flange portion 23 and the second flange portion 24 restrict the movement of the coil 16 provided in the main body portion 22. Specifically, the coil 16 provided in the main body portion 22 is displaced in the radial direction of the stator core 15. Therefore, the first flange portion 23 and the second flange portion 24 are in contact with the coil 16 at the axial end portion of the main body portion 22, and the movement of the coil 16 is restricted. Each of the first flange portion 23 and the second flange portion 24 is formed in a ring shape so as to protrude radially outward from the main body portion 22. In other words, the first flange portion 23 is such that the edge portion on the inner peripheral side faces the main body portion 22. The first flange portion 23 is provided at an axial end portion of the main body portion 22. Specifically, the first flange portion 23 is located on the side opposite to the yoke portion 17 of the stator core 15 when the electric machine bobbin 21 is inserted into the tooth portion 18 of the 100114237 10 201218580. The first flange portion 23 has a plurality of engaged portions 25 on the inner peripheral side. When the first flange portion 23 is attached to the main body portion 22, the engaged portion 25 enters the fitting hole 22e formed by the main body portion 22. The engaged portion 25 is formed in a columnar shape corresponding to the matching hole 22e. The fitted portion 25 can be changed in shape according to the shape of the matching hole 22e. For example, when the cross section of the engagement hole 22e has a square shape, the engagement portion 25 is formed in a quadrangular prism shape. Similarly to the first flange portion 23, the second flange portion 24 is opposed to the main body portion 22 at the edge portion on the inner peripheral side. The second flange portion 24 is provided at the other end portion of the main body portion 22 in the axial direction, that is, the end portion opposite to the first flange portion 23. Specifically, the second flange portion 24 is located on the center side of the stator core 15 when the electric device bobbin 21 is fitted into the tooth portion 18. The second flange portion 24 is set such that the total length of the stator core 15 in the circumferential direction is smaller than that of the first flange portion 23. The reason for this is that the second flange portion 24 is located closer to the center side of the stator core 15 than the first flange portion 23. In other words, the electric machine bobbin 21 is fitted to the radially formed tooth portion 18 with respect to the center of the stator core 15. Therefore, the distance between the electric machine bobbins 21 adjacent to the circumferential direction of the stator core 15 is smaller toward the center side of the stator core 15, that is, the second flange portion 24 side. Therefore, in order not to bring the adjacent second flange portions 24 of the electric machine bobbin 21 into contact with each other, the second flange portion 24 is set such that the total length of the stator core 15 in the circumferential direction is smaller than the first flange. Part 23. Similarly to the first flange portion 23, the second flange portion 100114237 11 201218580 24 has a plurality of the engaged portions 25 on the inner peripheral side. When the second flange portion 24 is attached to the main body portion 22, the engaged portion 25 enters the fitting hole 22e formed by the main body portion 22. The shape of the engaged portion 25 of the second flange portion 24 is the same as that of the first flange portion 23. The second flange portion 24 may be curved concentrically with the outer surface of the rotor 13 on the side of the rotor 13. Further, the first flange portion 23 may be curved concentrically with the surface of the yoke portion 17 and the inner wall of the yoke portion 17. In particular, by making the surface of the first flange portion 23 on the yoke portion 17 side and the inner wall of the yoke portion 17 approximately curved, the end portion of the electric machine bobbin 21 on the side of the magnetic motor portion 17 can be made according to the magnetic vehicle. The inner wall of the portion 17 determines the position. The first flange portion 23, the second flange portion 24, and the engaged portion 25 are formed of a synthetic resin. Here, as the synthetic resin, for example, Polyphenylene Sulfide Resin (PPS resin), acrylonitrile-butylene-styrene copolymer resin, polyammonium resin, polyethylene terephthalate An alcohol ester resin, a polyacetal resin, or the like is preferred. The first flange portion 23, the second flange portion 24, and the engaged portion 25 are integrally formed with the main body portion 22 by, for example, insert molding. The thickness of the first flange portion 23 and the second flange portion 24 is arbitrary. In the first embodiment, the first flange portion 23 and the second flange portion 24 have a thickness T2 of 2 to 3 mm as shown in Fig. 14 . The thickness T2 of the first flange portion 23 and the second flange portion 24 is set to be as small as possible in a range where it is desired to be formed. By reducing the thickness Τ2 of the first flange portion 23 and the second flange portion 24, the main body 100114237 12 201218580 portion 22 of the electric machine bobbin 21 is enlarged in the axial direction. As a result, the number of turns of the wire wound around 22 is increased, and the lamination factor of the electric wire can be increased. The body portion engagement portion 25 is fitted to the engagement hole 22e of the main body portion 22 while being attached to the first flange portion 23 and the second portion. Thereby, the fourth forming portion 25 is formed separately from the first flange portion 23 and the second flange portion 24_the rabbit flange portion 24 by the first flange portion 23 and the second flange portion 24. When the fitting portion 25 is filled into the matching hole ❿, the first flange portion is bound to be engaged (4) into the matching hole 22e to be made: convex::24, the first flange portion 23 and the second flange portion 24, Connected to the main body 2 and connected. The bobbin 21 can be securely used, and the refill member 26 is provided as shown in Fig. 5 at 千26. The inner peripheral side of the inner peripheral side of the main body portion 22, the first true side, and the inner peripheral flange 邛24 of the second convex ridge h > I are filled with the main body portion 23 and the second flange portion 2 /, - The difference in backlash between the flanges of the flanges. This filling member 26 is formed of a material excellent in ',,,, and excellent properties. The % of the filling member is more desirably, for example, the heat-resistant resin or the increased the mobility of the lining temperature. Next, an insert molding die used for molding the above-described electric machine bobbin 21 will be described with reference to Fig. 12 . The insert molding die 31 shown in Fig. 12 is provided with a base portion 32 and a lower mold. 33 and upper mold 34. The lower mold 33 is provided above the base portion 32. The upper mold %, is also above the lower & 33. The base portion 32' holds the lower mold 33 and the upper mold 34. The base portion 32' has a stopper portion 35 for determining the position of the main body 100114237 13 201218580 portion 22 of the electric machine bobbin 21. The stopper portion 35 has a quadrangular prism shape having almost the same shape as the #18 portion of the stator iron. The base portion 32, r , , has a plurality of protruding pins 36 projecting upward. The protruding pin 36 is used to take out the formed bobbin 21 for an electric machine from +. The lower mold 33 lower mold 33 is composed of a pair of block-shaped movable lower molds 37. The lower mold 37 is disposed above the base portion 32, and moves along the base portion to move the upper surface of the movable z to open the mold. The arrow γ shown in Fig. 12 indicates the direction in which the mold is opened. The movable lower mold 37 has a slit 38 corresponding to a substantially half-rise of the electric machine bobbin 21. The movable lower die 37 is combined with the cavity 38 of the bobbin 21 for electrical equipment by combining these. Above the movable lower mold 37, a nozzle 39 for connecting the movable lower mold 37 and the cavity 38 is provided. For the illusion 9, for example, a resin such as a condensed PPS is supplied to the mold moon 38. The first flange portion ^ and the second flange portion 24 are formed of a resin supplied from the nozzle 39. The upper mold 34 has a spool 4 (through) that runs through the upper and lower threads. The resin of (4) is supplied to the nozzle % of the lower mold % by the spool liquid passage of the upper mold 34. A reservoir portion w connected to the wire bypass 4 () is formed at the upper end of the upper die 34. The molten resin supplied from the outside is stored in the reservoir 4 and the lower end of the line reduction 4 () is connected to the nozzle by combining the upper mold = the lower jaw 33: Next, referring to FIG. 13 for the plasma treatment Description. The plasma treatment is carried out by using a discharge generated by applying a high voltage of direct current or alternating current between the electrodes. The discharge generated by applying a high voltage is a corona discharge at atmospheric pressure or a glow discharge in a vacuum or the like. The insulating film forming the portion of the main body 100114237 201218580 is subjected to plasma treatment by exposure to the discharge generated thereby. The plasma treatment is preferably carried out in a vacuum having a wide selection of process gases. Further, the plasma treatment is used as a process gas, such as helium, neon, argon, nitrogen, oxygen, carbon dioxide gas, air, and water vapor, in a single or mixed state. Among them, argon gas and carbon dioxide gas are preferred because of the efficiency of discharge initiation. The treatment gas pressure in the plasma treatment is 0. The pressure range of 1 Pa to 1330 Pa is preferably in the range of 1 Pa to 266 Pa. The plasma processor 51 shown in Fig. 13 has a process chamber 52 that can be sealed. The processing chamber 52 accommodates the processing roller 53 inside. The electrode 54 is surrounded by a small gap formed around the processing roller 53. The processing roller 53, is grounded. The electrode 54 is connected to the high frequency power source 55. The processing chamber 52 is depressurized by opening the valve 56 which is internally connected to a vacuum pump (not shown). At the same time, the processing chamber 52 is supplied with a gas for processing by opening the valve 57 connected to a gas supply source (not shown). The processing chamber 52 is provided with a pressure gauge 58 for detecting the internal air pressure. The insulating film 42 wound in a roll shape is taken out from the supply portion 59. The extracted insulating film 42 is provided by a plurality of guide rolls 60 in the processing chamber 52. The guiding side is curled by the processing roller 53 for nearly one week. At this time, the insulating film 42, - passes through the treated portion between the electrode 54 and is subjected to plasma treatment there. Then, the plasma-treated insulating film 42 is taken up by the guide roller 60 while being taken up by the winding portion 61. At this time, the insulating film 42 is subjected to plasma treatment on one side or both sides of 100114237 15 201218580. When the single surface of the insulating film 42 is subjected to the plasma treatment, the surface subjected to the plasma treatment is disposed on the outer peripheral side of the main body portion 22. Next, a manufacturing procedure for the electric machine bobbin 21 will be described with reference to Fig. 12 . The insulating film 42 constituting the main body portion 22 is subjected to a surface treatment step. The surface treatment step is, for example, plasma treatment using the above-described plasma processor 51. The film-shaped insulating film 42 which has been subjected to plasma treatment is cut into a rectangular shape as shown in Fig. 12(a) and expanded into the shape of the main body portion 22. The length P of the long side of the insulating film 42 after cutting corresponds to the length of the upper side wall 22a in the left-right direction, the length of the left side wall 22d in the vertical direction, the length of the lower side wall 22b in the left-right direction, and the right side wall 22c. The length, if necessary, plus the length of the glued area. Further, the length Q of the short side after the cutting corresponds to the front-rear direction of the main body portion 22 and the length in the front-rear direction of the upper side wall 22a. Therefore, the thickness of the insulating film 42 is set to 0. 05~0. 5 mm. The insulating film 42 is formed with a hole corresponding to the fitting hole 22e at both ends of the long side when the shape of the main body portion 22 is formed or before the molding. The matching hole 22e may be formed after the insulating film 42 is formed into a predetermined shape, or the insulating film 42 may be formed before the forming of the matching hole 22e. Further, the formation of the insulating film 42 and the formation of the fitting hole 22e can be simultaneously performed by press working using a mold or the like. The formed insulating film 42 is formed into a shape corresponding to the body portion 22 of the main 100114237 16 201218580 as shown in Fig. 12(b). In the first embodiment, the insulating film 42 is formed into a rectangular tube shape. When the insulating film 42 contains the rubberized region, the insulating film 42 which is bent into a rectangular tube shape will have the glue application region on the upper side wall 22a or the lower side wall 22b. Further, when the main body portion 22 is molded, an adhesive or the like may be applied to the rubberized region to temporarily fix the insulating film 42 before insert molding. Thereby, the formed insulating film 42 is reduced in deformation at the time of insert molding. The step of forming the insulating film 42, forming the matching hole 22e, and forming the shape of the main body portion corresponds to the main body portion shaping step. As shown in FIGS. 12(c) and 12(d), the insulating film 42 which is formed into a cylindrical shape is fitted to the stopper portion 35 in a state where the lower mold 33 is opened, that is, in a state where the movable lower molds 37 are separated from each other. . The step of fitting the insulating film 42 to the stopper portion 35 of the lower mold 33 corresponds to the main body portion disposing step. The insulating film 42 formed into a cylindrical shape is slightly separated from the base portion 32 when being fitted into the stopper portion 35. By disposing the thus formed insulating film 42 and the base portion 32 separately, the resin at the time of insert molding is injected into the outer side of the end portion in the axial direction of the main body portion 22. As a result, the main body portion 22 is improved in strength at the end portion in the axial direction. When the insulating film 42 formed into a cylindrical shape is disposed on the stopper portion 35, the movable lower mold 37 is joined as shown in Fig. 12(e) to form the cavity 38. Thereby, the cylindrical insulating film 42 is housed in the cavity 38. This step is equivalent to the fixed step of the lower die. Step. When the insulating film 42 formed into a cylindrical shape is housed in the cavity 38, the upper mold 34 is attached to the upper surface of the lower mold 33 as shown in Fig. 12(f). Then, the resin of the molten 100114237 17 201218580 is injected into the storage portion 41 of the upper mold 34. The resin injected into the reservoir 41 is supplied to the cavity 38 via the spool runner 40 and the nozzle 39. Thereby, the insulating film 42 formed into a tubular shape is insert-molded even if the main body portion 22 is an insert, and the main body portion 22 is integrally formed with the first flange portion 23, the second flange portion 24, and the engaged portion 25. . That is, the first flange portion 23, the second flange portion 24, and the engaged portion 25 are integrally formed with the main body portion 22 by the main body portion 22 as an insert by the injection of the molten resin. This step corresponds to the flange forming step. By the insert molding, the engaged portion 25 formed by the injection of the resin enters the fitting hole 22e of the main body portion 22. Therefore, the engaged portion 25 that integrally protrudes from the first flange portion 23 and the second flange portion 24 is brought into engagement with the engagement hole 22e. By subjecting the insulating film to a surface treatment such as plasma treatment in advance, the main body portion 22 can be improved in wettability and adhesion of the surface. Therefore, the molten resin forming the first flange portion 23 and the second flange portion 24 ensures the fluidity along the insulating film 42. As a result, the resin forming the first flange portion 23 and the second flange portion 24 adheres to the main body portion 22 in a sufficient range. Thereby, the main body portion 22 and the flange portion are sufficiently joined to reduce the cracking of the first flange portion 23 and the second flange portion 24 after molding. After the flange forming step of the insert molding, the upper die 34 is taken out from the lower die 33. Then, the movable lower mold 37 of the lower mold 33 opens the mold. At this time, the electric motor bobbin 21 is taken out from the base portion 32 by projecting the protruding pin 36 of the base portion 32 from the base portion 32. ] 〇〇] 14237 18 201218580 Furthermore, in the description of the above-described manufacturing steps, although an example of a surface treatment step such as plasma treatment before the main body portion shaping step has been described, the main body portion may be performed. After the shaping step, a surface treatment step is applied before the step of forming the flange portion. For example, the surface treatment may be performed on the insulating film 42 after the insulating film 42β is formed into a predetermined size. Further, a surface treatment step may be performed before the main body portion shaping step and after the main body portion shaping step, and before any of the flange portion forming step. Next, the steps of attaching the coil 16 to the tooth portion 18 of the stator core 15 will be described with reference to Figs. 1 to 4, 6, and 11. The electric machine bobbin 21 shown in Fig. 11 obtained by the above processing is wound around the outer periphery of the main body portion 22 with electric wires. Thereby, the electric machine bobbin 21 is provided with a coil 16 on the outer circumference of the main body portion 22 as shown in FIG. Further, the electric machine bobbin 21 is filled with a filling member 26 on the inner peripheral side of the main body portion 22. The electric machine bobbin 21 provided with the coil 16 and filled with the filling member 26 is fitted to the tooth portion 18 of the stator core 15 from the inner peripheral side of the stator core 15 as indicated by an arrow F in Fig. 6 . As a result, the coil 16 is in a state in which the bobbin 21 for electric equipment is clamped and is wound around the tooth portion 18. At this time, as shown in Figs. 1 to 4, the tooth portion 18 is housed on the inner side of the right side wall 22c and the left side wall 22d of the main body portion 22. On the other hand, the upper side wall 22a of the main body portion 22. The lower side wall 22b is located further outward than the entire length of the tooth portion 18 in the axial direction of the stator core 15. Further, the body portion 22 and the tooth portion 18 are filled with the filling member 26. The stator core 15 is provided with a bobbin 21 for an electric machine provided with a coil 100114237 19 201218580 16 to all the tooth portions 18. Here, the lamination factor of the electric wire will be described with reference to Fig. 14 . The conventional electric machine bobbin 101' shown in Fig. I4(b) is formed by, for example, injection molding or the like, and the main body portion 102 and the first flange portion 103 and the second flange portion 104 are seamlessly formed by the same resin. Be one. In this case, the thickness T 〇 of the main body portion 102 is required to be secured to a size at least not to be broken after the resin is integrally molded by the restriction at the time of molding. Therefore, the thickness T of the main body portion 102 is required to be, for example, TQ = 1~3 mm or so. On the other hand, in the case of the present embodiment, the right side wall 22c and the left side wall 22d of the main body portion 22 are made of a thickness T of 1 = 0. 05 mm~0. 5 mm of insulating film is formed. Therefore, the laminated factor of the electric wire of the electric device bobbin 21 of the present embodiment can be increased by the amount corresponding to (To-Ti) as compared with the conventional electric machine bobbin 101. Also, 'normally, when the current 1 (A) flows through the circular coil conductor, the magnetic flux density B at the center of the coil axis is "B = /z〇Nl/2r: where, #〇 is the magnetic of the vacuum. The conductivity, N is the number of turns per lm, 1 is the length of the coil, and r is the radius of the coil. The main body portion 22 of the first embodiment is thinner than the conventional main body portion 102 as described above. Therefore, the radius r of the coil 16 provided on the outer circumference of the main body portion 22 of the first embodiment is smaller than the radius r 习 of the conventional coil by a factor of (τ〇 - Τι). As a result, the coil 16 of the electric device bobbin 21 of the first embodiment can be used to improve the magnetic flux density as compared with the conventional one. Therefore, the electric machine bobbin 21 of the first embodiment can also improve the rotational efficiency of the rotary electric machine u from the viewpoint of the magnetic flux density 100114237 20 201218580 degrees. According to the first embodiment described above, the main body portion 22 of the electric device bobbin 21 that is fitted into the tooth portion 18 of the stator core 15 has a thickness of the right side wall 22c and the left side wall 22d of 〇 〇 5 to 〇. 5 mm insulation film. • Therefore, the thickness of the right side wall 22c and the left side wall 22d of the main body portion 22 is thinner than the bobbin formed by conventional insert molding. Therefore, more electric wires can be wound around the main body portion 22 of the bobbin 21 for electric machines, and the lamination factor of the electric wires can be increased. Further, since the main body portion 22 is thinned, the heat generated by the electric wires is easily transmitted to the stator core 15 via the thin main body portion 22. Therefore, the heat generated by the electric wires can be rapidly diffused to improve the heat dissipation. By improving heat dissipation, the rotary electric machine 11 can achieve high rounding and high efficiency. The t-machine shaft 21 of the first embodiment has a fitting hole 22e at the end portion of the main body portion 22 in the axial direction. The first flange portion 23 and the second flange portion 24 provided at the axial end portions of the main body portion 22 allow the engaged portions to enter the engagement holes 22e, respectively. Thereby, the joint strength between the main body portion 22 and the first flange portion 23 and the main body portion 22 and the second flange portion 24 are joined with high strength. Therefore, the falling of the first flange portion 23 and the second flange portion 24 from the main body portion 22 can be reduced. In the first embodiment, the first flange portion 23 and the second flange portion 插入 are insert-molded by the main body portion 22 as an insert. Therefore, even when the main body 与 22 and the first flange portion 23 and the second flange portion 24 are made of different materials, the manufacturing can be facilitated. At the same time, a sufficient thickness can be secured by inserting the flange portion 23 and the second flange portion 24 of the first 100114237 21 201218580. Therefore, the strength of the first flange portion 23 and the second flange portion 24 can be improved. Further, the main body portion 22 is integrally joined to the first flange portion 23 and the second flange portion 24. Therefore, even if the materials are formed of different materials, the electric machine bobbins 21 can be easily attached to members such as the stator core 15. In the first embodiment, the filling member 26 is provided on the inner peripheral side of the main body portion 22. The filling member 26 fills the height difference between the main body portion 22 and the first flange portion 23 and the second flange portion 24. Thereby, when the electric machine bobbin 21 is attached to the tooth portion 18, the gap between the main body portion 22 and the tooth portion 18 is filled with the fluid filling member 26. Therefore, the thermal energy generated by the electric wires constituting the coil 16 is transmitted from the filling member 26 to the stator core 15 via the main body portion 22. Therefore, the heat dissipation of the coil 16 can be improved, and the temperature rise of the coil 16 can be suppressed. In the first embodiment, the surface of the insulating material is subjected to a surface treatment for improving the wettability before the main body portion forming step or after the main body portion forming step and before the flange portion forming step. Thereby, when the insert is formed, the molten resin of the first flange portion 23 and the second flange portion 24 is formed to easily flow along the insulating material forming the main body portion 22. Thereby, the resin forming the first flange portion 23 and the second flange portion 24 and the insulating material forming the main body portion 22 can ensure high adhesion. Therefore, the joint strength between the main body portion 22 and the first flange portion 23 and the second flange portion 24 can be improved, and the crack or the like after the forming can be reduced. 100114237 22 201218580 (Second Embodiment) Fig. 15 shows an important portion of the bobbin 21 for electric equipment according to the second embodiment. The first flange portion 23 and the second flange portion 24 have a substantially symmetrical structure. Therefore, the periphery of the first flange portion 23 is illustrated in Fig. 15, and the illustration and description of the second flange portion 24 are omitted. The first flange portion 23 has a pair of holding pieces 23a as shown in Fig. 15 . A pair of holding pieces 23a are provided at positions sandwiching the main body portion 22 in the thickness direction of the main body portion 22. The holding piece 23a is integrally molded with the same resin as the first flange portion 23 simultaneously with the first flange portion 23. One of the pair of holding pieces 23a is located on the inner side in the radial direction of the main body portion 22. The other of the holding pieces 23a is located on the radially outer side of the main body portion 22.
